The Factory Pro O-XCP008 Scythe Type option upper deck is an aftermarket hop-up for the Xray T4-21 chassis that lets you modify upper chassis stiffness and tune balance while leaving the main drivetrain unchanged.
This upper deck changes the load route between shock towers and the chassis centre, helping you refine flex characteristics for varying track conditions. Tackle tuning in small steps and measure lap times and handling after each adjustment to isolate effects.
An option part aimed at hobbyists wanting to alter chassis flex and balance on the Xray T4-21; always confirm correct fit and any needed fasteners before track sessions.
